An object of the present invention is to provide a front fork with a double-rod damper, which can improve an efficiency of an assembly operation thereof by simplifying alignment work of piston rods on assembly. To achieve this object, a front fork (30) comprising: an outer tube (1); an inner tube (2) inserted expansibly and contractibly into the outer tube; a double-rod damper (70) disposed inside the outer tube and the inner tube, the double-rod damper including a cylinder (3), a piston (5) received in the cylinder, a first piston rod (6) and a second piston rod (7) extending respectively from each side of the piston and penetrating through the cylinder, wherein an upper chamber (3a) and a lower chamber (3b) are defined between the cylinder and the piston, into which that oil is contained; and a fork-inside oil chamber (71) defined by the outer tube, the inner tube, and the double-rod damper, into which oil and air are contained, the double-rod damper further including: a piston rod connection mechanism (80) that connects at least one of the first piston rod and the second piston rod to the piston such that the one is displaceable in a direction perpendicular to an axis of the piston.
